Wrenches For Jar-Top Sprinkler Valves - Hunter and Irritrol

thingiverse

These are wrenches for Hunter and Irritrol jar top sprinkler valves. Sometimes sprinkler system valves are installed in underground boxes with little room to work. Getting tools on the jar tops to loosen/tighten can be a problem. I recently had to use a large set of channel locks to work on a valve, but it wasn't easy because of limited space. I could find no such specialized tools to help so I made these wrenches after the fact. These wrenches have been fit tested but not stress tested because I already fixed my valve. PLA and 15% infill seems good enough because once in place the jar top itself provides a lot of support to the tool, but I'm not ruling out the need to make the tool beefier. I have used Thingiverse for a long time and I am happy that I can finally contribute something.
